6 sanlock_selinux - Security Enhanced Linux Policy for the sanlock pro‐
7 cesses
8
10 Security-Enhanced Linux secures the sanlock processes via flexible
11 mandatory access control.
12
13 The sanlock processes execute with the sanlock_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep sanlock_t
20
21
22
24 The sanlock_t SELinux type can be entered via the sanlock_exec_t file
25 type.
26
27 The default entrypoint paths for the sanlock_t domain are the follow‐
28 ing:
29
30 /usr/sbin/sanlock
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 sanlock policy is very flexible allowing users to setup their sanlock
40 processes in as secure a method as possible.
41
42 The following process types are defined for sanlock:
43
44 sanlock_t
45
46 Note: semanage permissive -a sanlock_t can be used to make the process
47 type sanlock_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
51
53 SELinux policy is customizable based on least access required. sanlock
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run sanlock with the tightest access possi‐
56 ble.
57
58
59
60 If you want to allow sanlock to read/write user home directories, you
61 must turn on the sanlock_enable_home_dirs boolean. Disabled by default.
62
63 setsebool -P sanlock_enable_home_dirs 1
64
65
66
67 If you want to allow sanlock to read/write fuse files, you must turn on
68 the sanlock_use_fusefs boolean. Disabled by default.
69
70 setsebool -P sanlock_use_fusefs 1
71
72
73
74 If you want to allow sanlock to manage nfs files, you must turn on the
75 sanlock_use_nfs boolean. Disabled by default.
76
77 setsebool -P sanlock_use_nfs 1
78
79
80
81 If you want to allow sanlock to manage cifs files, you must turn on the
82 sanlock_use_samba boolean. Disabled by default.
83
84 setsebool -P sanlock_use_samba 1
85
86
87
88 If you want to dontaudit all daemons scheduling requests (setsched,
89 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
90 Enabled by default.
91
92 setsebool -P daemons_dontaudit_scheduling 1
93
94
95
96 If you want to allow all domains to execute in fips_mode, you must turn
97 on the fips_mode boolean. Enabled by default.
98
99 setsebool -P fips_mode 1
100
101
102
103 If you want to allow system to run with NIS, you must turn on the
104 nis_enabled boolean. Disabled by default.
105
106 setsebool -P nis_enabled 1
107
108
109
111 The SELinux process type sanlock_t can manage files labeled with the
112 following file types. The paths listed are the default paths for these
113 file types. Note the processes UID still need to have DAC permissions.

201 SELinux requires files to have an extended attribute to define the file
202 type.
203
204 You can see the context of a file using the -Z option to ls
205
206 Policy governs the access confined processes have to these files.
207 SELinux sanlock policy is very flexible allowing users to setup their
208 sanlock processes in as secure a method as possible.
209
210 STANDARD FILE CONTEXT
211
212 SELinux defines the file context types for the sanlock, if you wanted
213 to store files with these types in a different paths, you need to exe‐
214 cute the semanage command to specify alternate labeling and then use
215 restorecon to put the labels on disk.
216
217 semanage fcontext -a -t sanlock_exec_t '/srv/sanlock/content(/.*)?'
218 restorecon -R -v /srv/mysanlock_content
219
220 Note: SELinux often uses regular expressions to specify labels that
221 match multiple files.
222
223 The following file types are defined for sanlock:
224
225
226
227 sanlock_conf_t
228
229 - Set files with the sanlock_conf_t type, if you want to treat the
230 files as sanlock configuration data, usually stored under the /etc di‐
231 rectory.
232
233
234
235 sanlock_exec_t
236
237 - Set files with the sanlock_exec_t type, if you want to transition an
238 executable to the sanlock_t domain.
239
240
241
242 sanlock_initrc_exec_t
243
244 - Set files with the sanlock_initrc_exec_t type, if you want to transi‐
245 tion an executable to the sanlock_initrc_t domain.
246
247
248
249 sanlock_log_t
250
251 - Set files with the sanlock_log_t type, if you want to treat the data
252 as sanlock log data, usually stored under the /var/log directory.
253
254
255
256 sanlock_unit_file_t
257
258 - Set files with the sanlock_unit_file_t type, if you want to treat the
259 files as sanlock unit content.
260
261
262
263 sanlock_var_run_t
264
265 - Set files with the sanlock_var_run_t type, if you want to store the
266 sanlock files under the /run or /var/run directory.
267
268
269 Paths:
270 /var/run/sanlock(/.*)?, /var/run/sanlk-resetd(/.*)?
271
272
273 Note: File context can be temporarily modified with the chcon command.
274 If you want to permanently change the file context you need to use the
275 semanage fcontext command. This will modify the SELinux labeling data‐
276 base. You will need to use restorecon to apply the labels.
277
278
280 semanage fcontext can also be used to manipulate default file context
281 mappings.
282
283 semanage permissive can also be used to manipulate whether or not a
284 process type is permissive.
285
286 semanage module can also be used to enable/disable/install/remove pol‐
287 icy modules.
288
289 semanage boolean can also be used to manipulate the booleans
290
291
292 system-config-selinux is a GUI tool available to customize SELinux pol‐
293 icy settings.
